Will it keep working?
✅ Future-proofBuilt to keep working — even if the maker walks away.
It works locally over Z-Wave, so it keeps running even if Alarm.com shuts down the app or the servers. Nothing here ties you to a single company's survival.
- Works locally over Z-Wave — keeps running without the maker's cloud
- Still in production
- Companion app is actively updated
Based on how this device connects (local vs. cloud), whether it’s still sold and supported, and its app / subscription. A guide, not a guarantee.
